This substance does not materially affect the membrane itself or its postganglionic nerves. It produces a block of transmission of nerve impulses across the superior cervical ganglion. The ganglionic stimulating action of acetyicholine is also blocked, but that of potassium ion is not. Unlike curare, many other quaternary ammonium compounds, and nicotine, tetraethylammonium ion has no actions except this specific ganglionic blocking action over a wide range of doses. 1946 by The American Society for Pharmacology and Experimental Therapeutics
